What's a good name for an Enum for Yes & No values

Question

Background

In a C# command-line app I'm writing, several of the parameters have "yes" and "no" as the possible values.

I am storing their input using the Enum type shown below.

enum YesNo
{
     Yes,
     No
}

Which is fine - the code works. No problem there.

NOTE: Yes, I could store these as bool (that's how it used to work). My design choice is to be explicit about the Yes/No choice made by the user because they will see this printed in other contexts and I'd like it to be more obvious what the choice was.

My Question

• It just seems odd to have an enum called "YesNo" - what are some suggestions for better names for an enum for "yes" and "no" values.

So Finally

I asked this question relatively early in StackOverflow's life. It wasn't fake question - I really did have this situation. I just thought it would be nice to use it see what the community would do. Because it is, I admit a somewhat odd question.

First, thanks to all who spent the time replying. I'm trying to pay that back with a thoughtful conclusion.

Comments on the answers

switching to bool. I understand your motivation, but I feel I need to point out that having a binary choice (and by that I mean a choice between any two values - alive/dead, married/unmarried, etc.) is not the same as boolean choice between true and false. We find as programmers switching between yes/no and true/false easy - fair enough. Had my choice in this case been for example "Democrat" or "Replication"" (contrived example, I know) then you can see possibilities for confusion or at least awkwardness. I do think the bool option is valid in this case, but less so in other binary choices.

localization - great point. In my specific case it didn't matter - this was not and is never going to be localized, but for other situations it is something to consider.

more than three options - In fact, later on I had to add a third value called to represent the valid (in my application) condition of a user specifically not making the choice.

There were a lot of good comments, thank you all!

Answer 1

I'd suggest you use a name that indicates the Value which is set to Yes or No.

E.G.

public enum Married
{
    YES,
    NO
}
